Electron-positron pair creation induced by multi-pulse train of electric fields: effect of randomness in time-delay
Deepak Sah, Manoranjan P. Singh
We investigate the creation of electron-positron pairs (EPPs) in a sequence of alternating-sign, time-dependent electric field pulse trains by solving the quantum Vlasov equations.…

Vacuum polarization current in presence of intense Sauter field
Deepak Sah, Manoranjan P. Singh
The quantum vacuum becomes unstable under an external field, leading to spontaneous particle-antiparticle pair creation. In canonical quantization, the time-dependent particle numb…

Dynamical Scaling in Pair Production for Scalar QED
Deepak Sah, Manoranjan P. Singh
We report on the dynamical scaling of momentum spectra for particle-antiparticle pairs at finite times within the framework of scalar Quantum Electrodynamics (QED). The analysis fo…
